Fortune reporter Chris Morris explores how the Event Horizon Telescope has captured the first image of a black hole. “We’ve demonstrated that the EHT is the observatory to see a black hole on an event horizon scale,” says Haystack postdoc Kazunori Akiyama. “This is the dawn of a new era of black hole astrophysics.”
WBZ-TV’s Ken MacLeod visits MIT’s Haystack Observatory to learn about how scientists there processed enormous quantities of data to develop the first image of a black hole. “My goodness, we just proved that Einstein was right at a scale that no one has dreamed of,” says Haystack’s Michael Hecht. “Most of us still don’t believe it’s possible, even though we have done it.”
MassLive reporter Kristin LaFratta spotlights how researchers from the MIT Haystack Observatory played a key role in processing the first image of a black hole. “This project has been my life ever since the beginning of it. It’s overwhelming,” says Haystack’s Michael Titus. “It’s something that’s been a long time coming.”
Haystack research scientist Vincent Fish speaks with Radio Boston about the significance of capturing the first image of a black hole. “It seemed like it would take forever for us to constitute an array to actually be able to make an image,” recalls Fish of the early days of the project. “Actually making an image, I’m glad to be able to do that.”
Boston Globe reporter Martin Finucane spotlights how MIT Haystack Observatory researchers played a “major role in the effort to create the first-ever picture of a black hole.” “I’m very proud,” says Vincent Fish, a research scientist at Haystack. “I’ve spent most of my professional life on this and I’m just really glad we got such great results out of this.”
Prof. Nergis Mavalvala speaks with Ira Flatow of Science Friday about how she and her colleagues are working on a new technology called squeezed light, which could enable LIGO to see even more of the cosmos. Mavalvala explains that squeezed light is “a somewhat exotic quantum state of light that we engineer in our labs to improve the sensitivity of LIGO.”
Postdoctoral fellow Dheeraj Pasham speaks with Ira Flatow of Science Friday about his research calculating that a supermassive black hole 300 million light years from Earth is spinning at half the speed of light. Pasham explains that a black hole's spin rate provides information about the “channel through which it grew, all the way from a couple of years after the Big Bang until now.”
Space.com reporter Mike Wall writes that researchers have calculated a supermassive black hole’s rotation rate by analyzing the X-rays it emitted after consuming a nearby star. The researchers found that “the huge black hole, known as ASASSN-14li, is spinning at least 50 percent the speed of light.”
Gizmodo reporter Ryan Mandelbaum writes that researchers determined how fast a supermassive black hole spins by measuring a star being swallowed by the black hole. Postdoctoral fellow Dheeraj Pasham explains that, “this measurement is different in the sense that we were able to measure the spin of a black hole that was dormant.”
Astronomers from MIT have detected echoes in X-ray flares emitted by a black hole consuming stellar material, writes Charles Q. Choi for Space.com. The findings “might shed light on how matter behaves not just as it falls into stellar-mass black holes,” writes Choi, “but also supermassive black holes millions to billions of times the mass of the sun.”
BBC News reporter Jonathan Amos writes that LIGO (operated by MIT and Caltech) and Virgo researchers have detected gravitational waves emanating from the largest black hole merger ever detected. Amos notes the discovery was announced by the collaboration as part of an “expanded catalogue” of detections that “tells us something about the probable future successes of the laser laboratories.”
A new study co-authored by Assistant Prof. Salvatore Vitale shows that the collision of a black hole and neutron star could provide insight into how quickly the universe is expanding. One such merger could allow physicists to calculate the expansion rate “as effectively as combining data from 50 different neutron-star collisions,” reports Meghan Bartels for Space.com.
A new paper by Assistant Prof. Salvatore Vitale finds that studying the rare pairing of a neutron star and a spiraling black hole could allow researchers to determine the universe’s rate of expansion, writes Jeremy Fox of The Boston Globe. The positive detection of a collision could “potentially give a dramatic contribution to our understanding of the universe,” says Vitale.
An international research team led by postdoctoral fellow Carl Rodriguez has found that within a group of star clusters, black hole collisions can actually create larger black holes, writes Nola Taylor Redd for Fox News. A simulation showed that these black holes “should grow to be more than 50 times as massive as Earth's sun if they collide with other black holes.”
Research led by Dheeraj Pasham, a postdoc at MIT's Kavli Institute, provides evidence “that black holes feed on passing stars then eject energetic jet streams,” writes Laney Ruckstuhl for The Boston Globe. “Such black hole jet streams can have large implications for the galaxies they enter. Pasham said they can regulate the growth of a galaxy because of their energy levels."
